Description

The The present invention relates to a dispenser according to the preamble of claim 1.

Under The term "dispenser" is in the present Invention in particular to understand a dispensing head, preferably especially on a container or its output valve or attached to a hand-operated pump or attachable. In particular, it can also be a pressure vessel, a Dispenser pump o. Like. Act. The dispenser serves the non-spraying or delivery of a preferably cosmetic liquid.

Under the term "cosmetic Liquid "are in a narrower Sense cosmetics, hairspray, hair lacquer, a deodorant, a foam, in particular shaving cream, a gel, a paint spray, a sun or Skincare o. The like. Understand. Preferably, in one other sense but also other personal care products, cleaning products, o. Like., And also suspensions and fluids, especially with gas phases, includes. Next you can as other liquids, For example, air freshener, and especially technical Liquids and Fluids, such as rust remover o. The like., Can be used. However, for simplification reasons and below Due to the focus of use often only cosmetic liquid spoken.

at today's dispensing devices for dispensing in particular foaming or foamed Liquids, such as shaving cream, or donor pumps is often the Problem that the liquids leak after the actual delivery later, especially nachschäumen or drip. This problem is particularly in shaving foam or the like. blatant, but also occurs in non-foamed or non-foaming liquids in particular, and may cause unwanted contamination of the Lead dispensers.

Of the present invention is based on the object, a dispensing device indicate an afterthought Leakage of liquid, especially a re-foaming, avoids or minimizes.

The The above object is achieved by a dispensing device according to claim 1 solved. Advantageous developments are the subject of the dependent claims.

One Aspect of the present invention is that an outlet channel a opening to the outside or downstream - so on the outlet side - has arranged outlet opening, the from the exhaust valve lockable is. The exhaust valve So it is downstream or outlet side arranged. So it can be prevented that liquid subsequently - especially So after closing the dispenser - exit. In particular, such a Nachschäumen, the strongest so far in shaving foam or the like. occurs, avoided become.

The Dispenser serves a non-spraying discharge of the liquid. In particular, therefore, there is no sputtering or spraying, but preferably a relatively slow one Delivery with at least a relatively low delivery rate. The liquid In particular, therefore, it is not output as a beam.

The liquid is particularly preferably foamed or is self-foaming. Particularly preferred is shaving foam or the like. The issued or dispensed liquid but it can also be a relatively high one viscosity exhibit and / or even in pasty Form are issued.

One Another aspect of the present invention is that the exhaust valve a valve body which, depending on from the upcoming fluid pressure is movable, so that the outlet valve when crossing a minimum pressure opens. This ensures that a Fluid delivery always only takes place when actually a tax desired is, so the upcoming fluid pressure relatively high is. On the other hand, such an undesirable liquid dispensing be prevented.

at a liquid that foams, for example, by air contact, the minimum pressure is preferably higher than the foaming pressure and / or becomes the liquid in the outlet channel hermetically sealed to prevent the unwanted re-foaming the outlet or through the outlet opening prevent.

Further Advantages, features, characteristics and aspects of the present invention arise from the claims and the following description of preferred embodiments with reference to the drawing. It shows:

1 a schematic section of a proposed dispensing device according to a first embodiment;

2 an enlarged section of 1 with opened exhaust valve;

3 a schematic section of a proposed dispensing device according to egg ner second embodiment; and

4 an enlarged section of 3 , with opened exhaust valve.

In not to scale, only schematic figures will be for the same or similar parts the same reference numerals used, with corresponding or comparable Properties and advantages are achieved, even if a repeated Description is omitted.

1 shows a schematic section of a proposed dispensing device 1 , here as a dispensing head for dispensing a liquid 2 is formed in the aforementioned sense.

In particular, the dispensing device 1 for non-spraying delivery of the liquid 2 educated. In particular, an output of the liquid takes place 2 as a foam 3 , preferably as shaving cream or the like, as shown schematically in FIG 2 indicated. The liquid 2 For this purpose, it is particularly self-foaming and / or is foamed during dispensing.

However, the liquid can 2 basically be delivered in the non-foamed state and in particular also be non-foaming. In particular, a lotion can also be used as a liquid 2 be issued. Further, it is also possible that the liquid foams only very slightly, so that foaming, for example, only slightly increases the volume, but essentially maintains a liquid or pasty consistency in the delivery.

The dispenser is preferably with a reservoir 4 for the liquid to be dispensed 2 provided or connected. The reservoir 4 So it can be part of the dispenser 1 form or can be connected to this.

In the first embodiment, the reservoir is 4 as preferably rigid container, in particular as a pressure vessel formed.

The liquid 2 in the reservoir 4 is either pressurizable or under pressure. In particular, the container or the liquid contains 2 a suitable propellant, preferably a volatile and / or flammable propellant, compressed gas and / or carbon dioxide.

In the first embodiment, the container is in particular elongate and / or cylindrical and / or rigid - particularly preferably as a metallic tin - for the liquid 2 designed and has particularly preferably the front side a dispensing valve 5 on, to which the dispenser 1 or the dispensing head formed thereof is connected.

2 shows in a partial enlargement of 1 the dispenser 1 or the dispensing head formed thereof more clearly with the exhaust valve open 2 with discharged foam 3 but without liquid 2 in the outlet channel 6

The dispenser 1 has an outlet 6 and an associated exhaust valve 7 on. The outlet channel 6 has a preferably open to the outside or downstream outlet opening 8th on. By the term "open to the outside" is meant in particular that no nozzle, no further channel or the like. followed. Rather, the liquid can 2 after exiting the outlet opening 8th preferably directly recorded or used by a user, not shown.

The exhaust valve 7 is preferably the outlet opening 8th assigned, so that these from the exhaust valve 7 is closable.

The exhaust valve 7 preferably has a valve body 9 on, which is movable in response to the upcoming fluid pressure, so that the exhaust valve 7 when a minimum pressure is exceeded, in particular only by the fluid pressure opens.

Particularly preferably, this minimum pressure is higher than a foaming pressure of the self-foaming liquid 2 , On the other hand, then the discharge pressure (with open dispensing valve 5 ) And thus the upcoming liquid pressure in turn higher than the minimum pressure, so that the desired liquid delivery and production or output of the foam 3 then the exhaust valve 7 opens.

In the first embodiment, the opening of the discharge valve takes place 5 preferably by depressing the dispenser 1 or the dispensing head formed thereof. The dispensing valve 5 closes when released then again independently. However, the dispensing valve may be 5 for example, to a metering valve or the like. act.

The valve body 9 is preferably formed substantially cylindrical, in particular in 2 indicated. The valve body 9 preferably has an annular bead or in particular a substantially conical sealing portion 10 on, with the exhaust valve closed 7 sealing with a valve seat 11 the exhaust valve 7 in particular from the outlet opening 8th formed or disposed immediately adjacent thereto, cooperates. If necessary, the valve seat 11 also from one to the outlet 8th subsequent section 12 the outlet channel 6 be formed.

In the illustrated example, the dispenser 1 or the outlet channel 6 preferably a valve body 9 surrounding ring channel 13 on, to which the tapered in cross-section or reduced outlet channel section 12 with the outlet opening 8th followed.

The valve body 9 is preferably made of elastic material, particularly preferably an elastomer or polymer. In the illustrated example, the valve body 9 injection molded.

In the illustrated example, the valve body 9 preferably via an elastically deformable, in particular ring-like holding section 14 held in particular axially movable. Particularly preferred is the valve body 9 one-piece with the holding section 14 formed or molded on this.

The valve body 9 is preferably over the holding section 14 and / or a fastening section 15 held. In the illustrated example, the attachment section closes 15 at the preferably reduced in its thickness holding portion 14 and / or surrounds this. Particularly preferred is the attachment portion 15 at the dispenser 1 fastened, in particular with a component 16 as a shell, the dispenser 1 firmly connected. Particularly preferred is the attachment portion 15 to the dispenser 1 or its component 16 molded or molded. Particular preference is given to a so-called "bi-injection", that is to say in particular injection molding of a further material in the same injection mold, in which a first material is formed.

In the illustrated example, the attachment portion 15 , the holding section 14 and the valve body 9 in particular integrally formed and / or made of the same, preferably elastic material, in particular plastic, particularly preferably by the said "bi-injection". However, there are also other constructive and / or manufacturing solutions.

The dispenser 1 has a lower part in the representation example 17 on that with the reservoir 4 or dispensing valve 5 connected or connectable and / or the outlet channel 6 (possibly together with the component 16 or attachment section 15 ), the outlet opening 8th and / or the valve seat 11 forms. In the illustrated example, the upper part forming component 16 with the lower part 17 so connected or connected, that the outlet channel 6 in particular tight - preferably gas or airtight - covered or completed. Together with the preferably airtight exhaust valve 7 this has the advantage that after the first use of the dispenser 1 in the outlet channel 6 remaining liquid 2 - Even with prolonged storage or non-use of the dispenser 1 - Is not exposed or preferably at least only to a negligible extent the action of air or other external influences. In particular, it can thus be prevented that, for example, an automatically foaming liquid 2 , as usually used for shaving cream, in the outlet 6 foams up and undesirably from the delivery device 1 - escapes or swells out, especially over a long period of time.

For use, the dispenser 1 or preferably the dispensing head formed therefrom - preferably immediately and / or manually - depressed or otherwise operated, so that the dispensing valve 5 opens. The in the reservoir or container 4 preferably pressurized liquid 2 can then in particular via a riser 18 and the open dispensing valve 5 in the outlet channel 6 stream. Because of then in the outlet 6 prevailing or pending liquid pressure or discharge pressure opens the exhaust valve 7 , In the first embodiment, this is done by the valve body 9 from the outlet opening 8th out or out, wherein the holding portion 14 is elastically deformed accordingly. The liquid 2 can then through the open exhaust valve 7 or the outlet opening 8th escape to the outside or into the free and particularly preferably lather and the foam 3 form. 2 shows the dispenser 1 with the exhaust valve open 7 with the preferably from the discharged liquid 2 formed foam 3 in the area of the outlet opening 8th , The discharged liquid 2 or the foam 3 can then in particular manually removed by a user, not shown, in particular stripped or wiped.

The liquid dispensing ends when in the outlet channel 6 prevailing fluid pressure or the discharge pressure falls below the minimum pressure again, so that the exhaust valve 7 closes. This is the case when the dispensing valve 5 - in particular by releasing or automatic reset of Abga button - closes again. The closed or closing exhaust valve 7 then prevents that still in the outlet 6 located liquid 2 undesirably from the outlet port 8th subsequently emerges or foams out.

In the illustrated example, the closing of the exhaust valve takes place 7 preferably exclusively by elastic restoring forces of the holding section 14 , Additionally or alternatively, to close the exhaust valve 7 the valve body 9 also be associated with a restoring or closing spring, not shown.

To close the exhaust valve 7 can favor a certain pressure compensation be provided. In the illustration example, it acts in the ring channel 13 upcoming fluid pressure on the holding section 14 in the closing direction. The pressure compensation, the restoring forces and the closing behavior of the exhaust valve 7 depend in particular on the area ratios (the area of the holding section 14 to the cross section of the valve body 9 in the area of the system at the valve seat 11 ) and of the dimensioning and property of the holding section 14 from.

A particular advantage of the proposed solution is that in addition to avoiding the subsequent escape of liquid 2 , In particular, a Nachschäumens, even for the user a very simple cleaning is possible because the exhaust valve 7 preferably immediately the outlet opening 8th closes, so that in the closed state, a clean or easy-to-clean closure or liquid outlet is formed.

In the illustrated embodiment, the liquid dispensing occurs substantially opposite to the depression direction or opening direction of the dispensing valve 5 and / or at least substantially downwards or in the longitudinal direction or axial direction of the particularly preferably substantially cylindrical reservoir or container 4 , However, the output direction can in principle be in any direction, in particular also substantially horizontally and / or laterally or radially.

Another aspect of the illustrative example is that the valve body 9 preferably in or opposite to the dispensing direction of the liquid 2 and / or in the outlet opening 8th is movable.

It should also be mentioned that at the outlet opening 8th preferably no further liquid dispensing means such as a nozzle, channel or the like. followed. However, this does not exclude that, for example, a shell-like extension, housing-side depression or the like., In which the outlet opening 8th opens, can be provided.

It should be noted that instead of the exemplified discharge of the liquid 2 as a foam 3 basically also any other delivery of the liquid 2 - If necessary, as a pasty mass, as a gel, as a drop or as a jet or spray comes into question.

Hereinafter, another embodiment will be described with reference to FIG 3 and 4 explained in more detail to the 1 and 2 correspond, with only essential differences compared to the first embodiment will be discussed. The previous remarks and explanations therefore apply in particular supplementary or corresponding.

In the second embodiment, the liquid foams 2 not or is not foamed.

In the second embodiment, the dispenser is 1 with a preferably manually operable pump 19 , in particular a metering or dispensing pump, provided or connected thereto. By depressing the from the dispenser 1 formed dispensing head becomes the liquid 2 in the dosing channel 6 promoted and generates such a discharge pressure that the exhaust valve 7 opens and the liquid 2 over the outlet 8th is delivered. Upon release of the dispensing head, a preferably automatic reset takes place, wherein during the return movement, the dispensing valve 5 the pump 19 closes and an inlet valve 20 opens to new fluid 2 from the reservoir 5 in a pump chamber 21 the pump 19 to suck.

In the second embodiment, the exhaust valve prevents 7 in particular an undesired dripping of liquid 2 from the outlet channel 6 or from the outlet opening 8th ,

In the second embodiment, the exhaust valve 7 designed such that to open the valve body 9 in the outlet opening 8th or the upstream section 12 the outlet channel 6 moved back. as in 4 indicated. In particular, here is a substantially radial seal with the exhaust valve closed 7 between the valve body 9 or its annular bead or sealing portion 10 on the one hand and the outlet channel section 12 or valve seat 11 on the other hand formed (see 3 ).

The valve body 9 ends - especially when the exhaust valve is closed 7 - At least substantially in the plane of the outlet opening 8th , This applies in particular also to the first embodiment.

Alternatively, the valve body 9 also over the outlet 8th protrude outwardly, this is especially true in the first embodiment, particularly preferably with the exhaust valve open 7 , if necessary, but also with the exhaust valve closed 7 ,

Separate Features and aspects of the various embodiments may be arbitrary combined with each other or other dispensing devices o. Like. Be used.
